9 Questions
Transition metals obey the ______ rule instead of the octet rule due to the involvement of d orbitals
18-electron
Which statement is true about the electron configurations of positive ions formed by transition and post-transition elements?
They do not follow the octet rule.
In a diatomic molecule, the bond moment is the ______.
dipole moment
When transition and post-transition elements form positive ions, electrons are always lost first from the shells with the highest value of the ______ quantum number
principal
Which rule replaces the octet rule for transition metals?
The 18-electron rule.
The dipole moment of a polyatomic molecule depends on the ______ of the molecule.
geometry
Why do the atoms of transition and post-transition elements not usually obey the octet rule?
Because they do not have enough electrons to achieve the noble-gas configurations.
If the bond moments are equal in magnitude but opposite in direction, then they will ______ each other and the resultant dipole moment will be zero.
cancel
The positive ions of transition and post-transition elements do not have the usual noble gas valence shell electron configurations of ns2np6 and are not ______ with any of the noble gases
isoelectronic
